If you have a hacked website then trying to find vulnerabilities in the plugins you use is not the way to determine how the website has been backed, instead the evidence from the hack and the relevant logging should be scrutinized. Our hack cleanup service for WordPress websites includes doing that, as well as a lifetime subscription to this service.

On Sunday we had probing on our website for usage of the plugin WP Security Audit Log, which has 80,000+ installs according to wordpress.org, from what looked to be hackers. Considering that plugin is known to vulnerable we didn’t further check in to what was going on, which was a mistake, but one that other monitoring we do allowed us to rectify today.
